Ovarian stimulation for assisted reproductive technology is traditionally started in the early follicular phase. The essential rationale to allow timely follicle growth and oocyte pick up ensure synchronization of vitro cultured embryos with receptive period endometrium a fresh transfer cycle. Also, conventional thought suggested that recruitment happened only once around menstruation. Deeper u...

Introduction: Any disruption in Folliculogenesis cycle (FC) as a produces oocyte function, leads to ovulation diseases, like poly cystic ovarian syndrome (PCOS). Although, there have not been found any definite treatment for PCOS, there are some temporary methods to treat it. That’s including drug, surgery and also lasers as complementary. In addition, these methods not only do...

BACKGROUND Poor ovarian response and retrieval of no oocytes following ovarian stimulation for in vitro fertilization (IVF) is a challenging problem for both the patient and the clinician. FINDINGS Recent evidence indicates that folliculogenesis occurs in a wave-like fashion indicating that there are multiple follicular recruitment waves in the same menstrual cycle. This relatively new scient...

Thyroid follicles, the functional units of the thyroid gland, are delineated by a monolayer of thyrocytes resting on a continuous basement membrane. The developmental mechanisms of folliculogenesis, whereby follicles are formed by the reorganization of a non-structured mass of non-polarized epithelial cells, are largely unknown. Here we show that assembly of the epithelial basement membrane is ...

background & aim: fenugreek (trigonella foenum- graceum l.) is a medicinal and edible plant in the family fabaceae. the aim of this study was the effect of hydro-alcohol extract of fenugreek seed on reproductive system of female balb/c mice. experimental: the animals divided to five groups of ten members: control group, placebo and three experimental groups. at first all animals synchronize...

background: induction of ovulation in art is necessary for superovulation and the side effects of superovulatory drugs are debated. oxytocin as a natural hormone, have receptors and is synthesized by several reproductive organs. preovulatory presence of oxytocin receptor mrnas in granulosa cells indicating a role for oxytocin in follicular development. objective: the aim of the present study wa...
